Biomolecular condensates formed through phase separation have emerged as a central principle of cellular organization, enabling the dynamic regulation of gene expression, signaling, metabolism, and stress responses. While early conceptual advances in condensate biology have largely originated from animal and in vitro systems, plant cells present a unique set of biological and technical challenges, including rigid cell walls, turgor pressure, plastid autofluorescence, complex endomembrane organization, and acute environmental responsiveness. These distinctive features impede the direct transfer of existing methodologies and drive the development of heterogeneous experimental practices. In this community comment, we present a comprehensive methodological framework for studying biomolecular condensates in plants, spanning in silico prediction, in vitro reconstitution, molecular dynamics simulations, live-cell and super-resolution imaging, material property measurements, membrane-associated condensates, and synthetic condensate engineering. We highlight best practices, common pitfalls, and plant-specific considerations, emphasizing the need for orthogonal validation, quantitative interpretation, and physiological relevance. By consolidating current methodologies and articulating shared principles, this review aims to establish a foundation for rigorous, reproducible, and conceptually coherent research in condensate biology of plants and beyond, with emerging implications for crop genetic improvement and synthetic biology applications.

Plant cell walls are dynamic composite structures whose biogenesis, remodelling, and integrity maintenance require coordinated regulation across biosynthetic, trafficking, sensing, and signalling pathways. Plasma membrane-localised receptor kinases and mechanosensitive channels monitor wall status and transduce perturbations into intracellular responses, whilst biomolecular condensates, membrane-less or membrane-associated assemblies formed through liquid-liquid phase separation and related processes, have emerged as candidate organisational features of several of these pathways. Direct experimental evidence linking condensates to cell wall function nonetheless remains sparse, and for many systems it is unclear whether observed puncta represent bona fide phase-separated assemblies. In this review we survey cell wall biogenesis and integrity pathways during development and under stress and critically evaluate where condensates plausibly participate. To keep claims proportionate to the evidence, we apply an explicit hierarchy, classifying each system as direct, indirect, contextual, or speculative. On this basis, the RALF-pectin system, in which extracellular phase separation generates signalling platforms that recruit the receptor kinase FERONIA and its co-receptor LLG1 as client proteins, remains the only directly validated example; most other associations, including P-bodies, stress granules, and nuclear transcriptional condensates, appear to respond to osmotic stress or molecular crowding arising as secondary consequences of wall perturbations. We further assess how computational and artificial intelligence approaches might complement experimental work, alongside their present limitations for plant systems.
